Application filed August 9, 1907. Serial No. 387,888.

To all whom it may concern:

Be it known that we, AMBRosn HEATH- 000K and LEE RUSH, citizens of theUnited i States of America, residing atJackson, in the by the valve isnormally held closed.

county of Madison and State of Tennessee, have invented new and usefulImprovements in Engine-Governors, of which the following is aspecification.

This invention relates to overnors for expiosive engines using alcohokerosene, crude oil, gas or gasolene as the motive agent, the

object in view being to provide a governor ,mechanism of simpleconstruction with valve mechanism cooperating therewith to throttle andregulate the admission of gas and air or gas and the particularhydro-carhon employed in such a manner as to secure a sensitive oeration and to supply a proper amount'of uel to obtain an maintain asteady running action of the engine.

The invention consists of the novel features of construction andcombination of' parts hereinafter fully described and claimed, and isillustrated in the accompanying drawings, in which Figure 1 is avertical longitudinal section through the valve mechanism, and showingthe associated. governor, the latter being partly broken away, as itsfull illustration is not needed in this view. Fig. 2 is a top plan viewof the mechanism. Fig. 3 is an end elevation thereof. Fig. 4 is asectional view of the throttle valve.

Referring to the drawings, the numeral 1 designates an admission valvecasing, designed to be secured in any preferred manner to the enginecylinder 2, and provided with a sup ly port 3 communicating with a port4 lea ing to the combustion or explosive chamber of the engine. "lheexplosive mixture enters said casing through a feed passage 5communicating with a chamber 6 in the upper portion of the casing,- fromwhich the port 3 leads, the top of sa' chamber being closed by asuitable remo= rble cover 7. A vs .ve seat-8 is formed at th point ofjunction of the feed passage with th chamber 6 for an a lmission valve9, adapted to open under acuum formed by the piston on its out ,troke.The stem 10 of the valve slides in an opening in the bottom of thecasing and projects below the same, a coiled spring 11 being arrangedabout said stem between a nut 12 thereon and the bottom or" the casing,wl'ieiie- T re action of the spring may be regulated by adjusting thenut to control the action of the valve.

Secured in any suitable manner u on one side of the casing 1 is a chestor thrott e valve casing 13, provided with ayalve chamber 14, from whichleads a feed passage 15 connecting the same with the passage 5. Incommunication with the lower end of the chamber 14 is an air inlet 16opening through the bottom of the casing, and connected with the.

side of thecasing in any preferred manner is a pip'e 17 for the supplyof gas, when the latter is employed as a motive agent. the casingalongside the chamber 14 is a fuel pocket or chamber 18, designed toreceive a store or supply of gasolene or other suitable hydrocarbon,when such a fuel is used, the hydrocarbon being fed thereto through asupply pipe 19 entering one side of the pocket.

At the oppos te side of the pocket is an over-- flow pipe 20, throughwhich the hydrocarbon when passing above a determined level exhausts tothe exterior. In practice, the pipe 20 may lead back to the source of suply of the hydrocarbon, or the latter may be dis charged into anysuitable receptacle.

The hydrocarbon feeds from the pocket into the valve chamber through arestricted communicating port 21 governed by a needle valve 22 extendingto the exterior through a stuffing box 23, the outer end of thestem ofthe valve being provided with a knob 24 by which said stem may berotated to adjust the valve to cut off or regulate the size of the feedpassage. The valve stem has a screwthreaded engagement with the wall ofthe stuiiing box to effect its in and out adjustment, as will be readilyunderstood. When the valve 9 iso ened'by the formation of a vacuum undert re action of the engine piston,

a quantity of the gasolene is drawn from the] Formed in pocket throughthe port 21 into the chamber I 14 andthere commingles with the airsimultaneously drawn through the port 16, the two agents combining toform the explosive mixture which flows through the port 3 into thecombustion chamber of the engine. it will be understood that the passageof the gasolene through a minute feed port in the manner describedcauses its conversion into a spray or vapor, which readily coinmingleswith the in-drawn air.

Operating in the chamber 14 is a sliding throttle valve 15, pivotallyconnected with the lower end of a rod or stem 26 movable through anopening in a cover plate 27c0vering the normally open upper end of thevalve chamber and fuel pocket. This valve in action controls both theair inlet 16 and gasolene feed port21, thus simultaneously regulatingtheir admission at required periods to the combustion chamber of theengine. valve is of the hollow type, and is provided with a feed port 28to register with the gas supply pipe 17, so that it will regulate the admission of gaswhen this character of fuel is employed with air to formthe explosive mixture.

Arranged on one side of the admission valve'casing lis a hollow standard29 having a base fiange 3O suit-ably fastened to a 'sup- )orting flange31 projecting from the casing. Flournaled in this standard is the shaftor stem 32 of an ordinary centrifugal governor 33 having a groovedsliding collar 34 connected in the usual manner by links to the.

weighted arms of the governor. The lower end of the shaft is adapted tobe driven by.

miter gearing 34 from a shaft 35 receiving motion from the en inegearing, whereby the governor is operate A lever 36 is centrallyulcrufned upon. an arm 37 extending from the standard 39 and ispivotally connected at its outer end to the valve stem 26 and providedwith a yoked inner end of ordinary construction having nular groove inthe slic in and rotating collar 4 34, whereby said lever wi l he swun ina vertical plane as the collar rises an falls to transmit motion tothevalve 25. By this construction the operation of the-throttle valve bythe governor is accomplished in a simple manner so that the valve willbe adjusted to re ulate the feed of the explosive mixture to t e enginein accordance with the requirements of the latter, the amount of fuelbeingincreased when the engine is running below normal s eed anddecreased roportionately when t e normal speed is limited. A rod 37 ispivotally connected at its upper end to the collar engaging arm of thelever and slides through an opening in the arm 37, said rod beingthreaded at its lower end to receive a nut 38, between which and the arm37 is a spring 39 surrounding the rod ,and exerting its expansivepressure to resist upward movement of the collar 34. This spring opposesa resistance to the movement of the governor, and by means of the nutits resistance may be increased or diminished to regulate the action ofthe governor to adjust the valve to a greater or less degree, wherebyThe.

ins engaging the an' the speed of operation of the engine may becontrolled to' a nicety.

Having thus described the invention, what is claimed as new, is:

1. In a governor for explosive en ines, a casing having a feed passage,an air iIIlet and fuel inlets, a valve governing one of said fuelinlets, a hollow sliding valve controlling said passage and the inlets,saidvalve havin a side port to register With the other fuel i et, and agovernor controlling said hollow valve;

2. In a governor for explosive engines, a

casing rovided with a valve chamber having an out et port, air andgas'inlet ports com-- municati with the chamber, and a valved fuel inletifis o communicating with the chain her, a sliding throttle valve in thevalve chamber controlling the fuel port and air in let, said valve beinof hollow form and having an admission s ot to cooperate with the gasinlet, a stern connected with the valve, a governor, a lever operated bythe governor and connected with the stem, and means for opposing. avaried resistance to the movement 0 the lever.

'3. In a governor for explosive engines, a casing having a valve chamberprovided with air and gas inlets, and formed with a;

fuel pocket provided with a port opening into the chamber, a valvegoverning the port, a

sliding'throttle valve controlling the air inlet, gas inlet and feedport, and a governor for operating the valve.

4. In a governor for explosive engines, a

casing provided with a valve chamber havingan out municating with thechamber, and. a pocket et port, air and gas inlet ports comat one sideof the chamber and having a port communicating therewith and providedwith a fuel inlet, a sliding throttle valve in the valve chambercontrolling the fuel port and air inlet, said valve being of hollow formand having an admission slot to cooperate with the gas inlet, a stemconnected with the,
